Walkthrough

Added or updated top-level env_set entries in four browser manifest JSON files to declare CHROME_EXECUTABLE; three manifests set it to "$dir\\chrome.exe", and Thorium's path was changed to "$dir\\bin\\thorium.exe". No other logic, control flow, or public declarations were modified.

Changes

Cohort / File(s)	Summary
Env var additions bucket/chromium.json, bucket/supermium.json, bucket/ungoogled-chromium.json	Added top-level env_set with CHROME_EXECUTABLE set to "$dir\\chrome.exe"
Executable path update bucket/thorium.json	Updated env_set.CHROME_EXECUTABLE value from "$dir\\thorium.exe" to "$dir\\bin\\thorium.exe"

Estimated code review effort

🎯 2 (Simple) | ⏱️ ~10 minutes

• Verify JSON syntax and correct escaping of backslashes in each file.
• Ensure there are no duplicate top-level keys or conflicting env_set entries.
• Confirm thorium.exe location under bin matches the package layout.

Poem

🐰 I hop through manifests, tidy and fleet,
CHROME_EXECUTABLE set for installs to meet,
Thorium now rests in bin snug and trim,
Small changes, quick steps — a rabbit's bright whim,
Hooray for paths that lead to a win!
